Specification of Letters Patent.

Patented July 6,1915.

Application filed February 8, 1915. Serial No. 6,715.

To all whom it may concern Be i known that I, ALBERT MARKS, a

citizen of the United States, residing at Brooklyn, county of Kings,State of New York, have invented certain new and useful Improvements inStamps, of-which the following is a full, clear, and exact description.

My invention relates to improvements in hand stamps and has for itsobject to produce a new and improved stamp.

It further has for its object-to produce a stamp having one or morewings, which, as the stamp is operated, are thrown outward by a camaction between the wing and the main frame or standard.

It further has for its object to produce a stamp having a flat printingsurface and an inking pad which is withdrawn therefrom and appliedthereto by a combination of vertical and oscillating movements.

It further has for its object to provide a new means for securing thepad in place.

It further has for its object to provide a new guiding means for theprinting memher.

The following is a description of my invention, reference being had tothe accompanying drawings in which,

Figure 1 is a side elevation of a hand stamp embodying my invention.Fig. 2 is a view, partly in section, of the stamp in operated position.Fig. 3 is a view of certain internal details. Fig. 4 is an upward viewof the stamp with the parts in the positions shown in Fig. 2. Fig. 5 isa perspective detail of the pad-carrying means. Fig. 6 is a perspectiveview of a guiding means. Fig. 7 is a perspective view of one of the sideframes.

Referring more particularly to the draw ings, 1, 1 are side piecesrigidly secured by screws to a top cap 2, the cap and side piecesconstituting the frame or standard of the machine. From this top cap atube 3 rises, surrounding a plunger 4 to which is secured a handle 5.Between the plunger and the tube is a retracting spring 6 whose endsengage abutme'nts 7 and 8 carried by.

the plunger, and cap respectively so as to normally hold the plunger inelevated position. Connected to the lower end of the plunger and movingtherewith 'is a U- shaped yoke 9 in which is a fixed shaft 10 whichcarries revoluble printing wheels 11. The lower end of the yoke carriesa cross plate 12 on which is engraved type for printing a word, such asPaid. The printing wheels carry type for printing a date. To the yokeare connected movably pivoted wings 13, one of which carries an inkingpad 14. The side pieces 1, 1 carry in wardly projecting lugs 15 withwhich cam surfaces 16 on the wings engage during the first part of thedownward movement of the plunger. This engagement results in throwingthe wings outward somewhat, after which the cam surfaces 16 of the wingsengage the paper to be printed on and are thereby forced into thepositions shown in Fig. 2. The presence of the lugs 15 relieves thepaper from the first thrust, which is the hardest, and prevents injurythereto. On account of the presence of the word-printing plate 12, a,wide printing surface is presented, such that the inking pad 14, carriedby one of the wings 13, cannot well be applied and Withdrawn by amovement in a'true are. In order to easily apply and remove the pad fromthe type surfaces I'provide means for permitting it to move downwardlyduring the first movement of operation of the stamp and then swing itaway with a movement in an arc, and for securing the reverse movements.in the return movements of the parts. This means consists in providing apad-carrier or cradle 17 having elongated slots 18 through which passesa rod 19 secured to the wing 18. The upper end of the pad-carrier isprovided with two inward projections 20 the lower edges 21 of whichslant, as shown. The yoke is provided with recesses having cam surfaces22 coacting wi h the cam surfaces 21 of the projections.

When the parts are in normal position the cam surfaces 21 and'22 engageas shown in Fig. 3 holding the pad-carrier up and the pad 14 in. closeengagement with the type surfaces of the printing member. When theplunger 4 is depressed the two cam surfaces 21 and 22 at first separateallowing the padcarrier 17 to fall so as to withdraw the pad 14 from thetype surfaces by a downward movement in a substantially"verticaldirection, The wings 13 are then thrown out carrying the pad-carrier 17an'dpad 14 to one side, to the position shown in Fig. 2. During aportion of the latter movement the pad or pad-carrier 17 contacts withthe paper so as to lift its wing, as shown in Fig. 2. On the returnmovement the pad first swings toward the type faces through an arc untilthe surface 21 engages the sur face 22, whereupon a cam action takesplace drawing the pad 1e upwardly into engage ment with the printingfaces in the position shown in Fig. 3. These means permit the pad topass the flat printing plate 12.

In order to guide the printing members I provide the frames with slots23 affording guide surfaces, and secure to the upper part of the yoke aguide 24 coacting therewith. This keeps the type in proper alinementwith the side frames.

In order to secure the pad to the pad-carrier 14 I provide at the bottomof the carrier 17 a laterally projecting shelf 25 on which the padholder 26 rests. This shelf is provided with a tooth 27. The pad holder17 has a hook 28 whose nose can be swung behind said tooth 27 so as tolock the holder and its pad in place upon the carrier.

The cap portion of the frame has cam surfaces 29 and the wings have camsurfaces 30 coacting therewith, whereby when the cam surfaces 29 and 80engage on the upward throw of the plunger the wings 13 are forced inwardto the positions shown in Fig. 1 and are held in that position until theplunger is again depressed. The cam surfaces 29 and 30 insure the actionof the cam surfaces 21 and 22.

In operating the stamp the plunger is depressed by pressure on itshandle, the cam surfaces coacting first with the lugs and then with thepaper thrust the wings out-- ward, the pad carrier being permitted tomove downward and then in the arc of a circle by reason of the camsurfaces 21, 22, and the printing members being guided by the guidecoacting with guiding surfaces on the frame. On the return to normal thereverse action takes place.

As will be evident my invention permits of modifications of theembodiment above described Without departing from the spirit thereof orthe scope of the appended claims.

W hat I claim is:

1. In a hand stamp the combination of a printing member, a wing pivotedthereto, a frame in which said member moves, said frame having aninwardly projecting lug near its base and said wing having a cam surfacecoacting therewith to throw said wing outwardly. v

2. In a hand stamp the combination of a printing member, a wing pivotedthereto, a frame in which said member moves, said frame having twoinwardly projecting lugs near its base, and said wing having two camsurfaces coacting therewith to throw said wing outwardly.

3. A printing member having a laterally extending type surface, anoscillating wing pivoted thereto, a pad carrier movable longitudinallyrelatively to said wing and carried thereby, a pad on said carrier,means for moving said pad carrier longitudinally upward relatively tosaid wing as said wing swings inward.

4:. In a stamp, the combination of a frame, a printing memberreciprocating within the same, a wing pivoted to said printing member,an ink pad carrier, supported by said wing and longitudinally movablethereon, said carrier and said printing member having coacting camsurfaces holding said pad carrier in proximity to the printing faces ofsaid printing member when the printing member is retracted.

5. In a stamp, the combination of a frame, a printing memberreciprocating within the same, a wing pivoted to said printing member,an ink pad carrier, supported by said wing and longitudinally movablethereon, said carrier and said printing member having coacting camsurfaces holding said pad carrier in proximity to theprinting faces ofsaid printing member when the printing member is retracted, and camsurfaces on said frame and wing holding said wing in closed positionwhen said printing member is retracted.

6. In a hand stamp, the combination of a frame having vertical slots, aprinting member reciprocating in said frame, and laterally projectingguides carried by said printing member and extending into said slots andthrough the side members of said frame for keeping said printing memberin fixed alinement with said frame, said guides being located at the topof said printing member.

7. In a stamp, a pad carrier having a laterally extending portion, a padholder, resting on said portion, a stud projecting downward from saidportion and a hook on said pad holder engaging said stud, said hookbeing pivoted on said holder so as to swing parallel to the plane of thebottom thereof and the plane of said extending portion.
